Subj : problems with command line linker

Hello,

I am using borland C++, version 4.52.  I have a 16 bit dos application 
which builds and runs fine using the IDE.  I'm using the large memory 
model and linking to a library I wrote also built under the IDE 
(different project file), also large memory model.

I want to build this application using the command line tools ( bcc.exe 
and Tlink).  When I do this, the compile works fine but I get two types 
of linker errors which don't occur when building the application under 
the IDE


ERROR 1
<function name> defined in module control.cpp is duplicated in module 
sim_8904.cpp

I do have some duplicate names.  There are some routines in the library 
which the application is re-defining.  No problem for the IDE.

ERROR 2
Error: Fixup overflow at OPI_MAIN_TEXT:03F3, target = 
__urc_global_ocs_data in library file c:\urc\kernel23\bc_lib\runonpc.lib 
in module opi_main

The symbol __urc_global_ocs_data is defined public in one module and 
extern in numerous files included in the library.  I verified I'm 
compiling large by adding this to one application file

#if !defined __LARGE__
#error WRONG MODEL
#endif
The file compiles without error



Do you have any idea what is wrong?

Thanks!
Jack
